However, this isn’t Johnson’s first run-in with the law in terms of arrests or convictions.

According to the New Orleans Police Department, Johnson has had 12 felony arrests, 10 misdemeanor arrests and was on probation on charges of illegal carrying of a weapon from June 2011 through December 2012.

“This suspect’s record, with multiple illegal firearm charges -- including his arrest just last September -- which was just a month before the Camp Street shooting -- is nothing less than reprehensible, and the people of New Orleans deserve better,” said Superintendent Ronal Serpas. “I was stunned to learn that Johnson was on probation for a second illegal use of a weapon charge at the time he allegedly attacked this man.

“No one should escape the consequences of the criminal justice system enough times to be labeled as a ‘possible career criminal.’ I’ve been assured that it’s only a matter of time before this suspect’s accomplices in this disturbing crime are picked up,” Serpas said.

Johnson’s criminal record goes back as far as 2009 and earlier, according to information from the NOPD.

In June 2009, Johnson was arrested on charges of resisting an officer, illegal carrying of weapons, possession of stolen property and simple burglary. Before 2009, police said, he had been arrested on charges of flight from an officer, simple burglary, unauthorized use of a moveable, possession of stolen property, traffic violations, attachments, warrants, probation violation and auto theft.

Many of the charges on Johnson’s rap sheet appear to have been refused, according to NOPD.

In March 2010, he was arrested on charges of illegal carrying of weapons and illegal possession of stolen firearms. The illegal possession of stolen firearms charge was refused, but Johnson was convicted of the illegal carrying of a weapon charges. He received a six-month suspended sentence and served three weekends in the parish prison.

In May 2011, Johnson was arrested on another charge of illegal carrying of a weapon and a charge of felon with a firearm. The felon with a firearm charge was refused, but he pleaded guilty to the illegal carrying of a weapon charge. He received an 18-month suspended sentence and was on probation for 18 months.

The charges continued after about a month when Johnson was arrested in July 2011 on charges of possession of stolen property and armed robbery. Both charges were refused.

Less than a year later in May 2012, Johnson was arrested on charges of felon with a firearm, illegal carrying of a weapon and illegal carrying of a weapon while in possession of a controlled dangerous substance.

All of the charges from May 2012 were refused, the news release from NOPD said.
